Question A-006-005-011

Which of these measurements is a good indicator of VHF receiver performance in an environment of strong out-of-band signals?

Correct Answer

Two-tone Third-Order IMD Dynamic Range, 10 MHz spacing

Explanation

Two-tone, third-order intermodulation distortion (IMD) dynamic range measures a receiver's ability to handle strong out-of-band signals without generating in-band interference. A wider spacing (like 10 MHz for VHF) tests more realistic scenarios.
